super1: don't allow adding a bitmap if there is no space.

If the data is too close to the superblock there may be
no space for a bitmap.
If that happens, fail the adding of the bitmap rather than
corrupt data.

super1: make sure 'room' includes 'bbl_size' when creating array.

Because we then go ahead and subtrace bbl_size from room.

Fix parallel make problem.

When make is called with, for example,
   "make -j9 install install-system"
i.e. both install and install-systemd targets at the same
line and with high -j value,
then the same install.tmp file was used, and udev rules
ends up in systemd service files, or otherway around.
